Hi Hache,
If you want to appear that editable only in posts and pages you have to do following steps,
1. Open plugin.class.php (It is in click-to-change directory)
2. On line 18 and 27, replace following codeif (current_user_can('manage_options') && in_the_loop()){
with this oneif (current_user_can('manage_options') && in_the_loop() && is_singular()){
3. Save the file, now click to change will appear only in posts and pages
Let me know if you have any other issues
Thanks
